Thanks a heap for this. I'm still leaning towards this option, unless someone
comes up with a good solid reputable smtp binary.

Does someone else have some ideas on this? I notice in the manual there is stuff
about retry rules or something, but I'm not sure how it all works. Is it possible
to get failure notices sent to a local file or something? Can messages be left in
a queue or saved to files for easy retry if desired? Presumably default 4-hourly
or whatever retries need to be turned off and some other kind requested instead.

Cheers,

Ben.
